As an admirer of Thomas Young, you perform a double-slit experiment in his honor. You set your slits 1.07 mm apart and position your screen 3.73 m from the slits. While Young had to struggle to achieve a monochromatic light beam of sufficient intensity, you simply turn on a laser with a wavelength of 649 nm. How far on the screen are the first bright fringe and the second dark fringe from the central bright fringe? Express your answers in millimeters.
A block of mass m1 = 1.75 kg and a block of mass m2 = 5.90 kg are connected by a massless string over a pulley in the shape of a solid disk having radius R = 0.250 m and mass M = 10.0 kg. These blocks are allowed to move on a fixed block-wedge of ..
